Introduction
If you notice your climate control lights are out but the controls are still working, use this guide to replace the lights. The light bulbs used in the climate control buttons are HVAC bulbs and over time they will eventually go out and make it difficult to see the controls at night. In this guide I will show you how to replace them on a 2004-2005 7th generation Honda Civic. It is a relatively easy repair but it does take a while so have some time on hand.
Before you purchase the replacement bulbs, ensure they are compatible with your vehicle's voltage (typically 12V). LED bulbs are energy-efficient and longer-lasting, while halogen bulbs offer a more traditional look.
Before you begin the repair make sure your car is off.
Note: This guide applies only to 2004–2005 models. The 2001–2003 Honda Civic is slightly different so the procedure is not the same.
